# AuSetIOErrorHandler(3nas)

set handler for fatal IO errors

## Name

**AuSetIOErrorHandler** - set handler for fatal IO errors

## Synopsis

\#include \<audio/audiolib.h\>

**AuBool** (\***AuSetIOErrorHandler**(*server*, *handler*))()\
\
     **AuServer** \**server*;\
\
     **AuBool** (\**handler*)(**AuServer** \*);

## Arguments

- *server*

  Specifies the connection to the audio server.

- *handler*

  Specifies the fatal error handler. Use NULL to reinstall the default fatal error handler.

## Description

**AuSetIOErrorHandler** sets the fatal I/O error handler and returns the previous error handler. The error handler will be invoked if a system call error occurs (for example, the connection to the server was lost). As this is assumed to be a fatal condition, the error handler routine should not return. If the I/O error handler does return, the client process exits.
